A woman is dead after her mobility scooter was hit by a transport truck on Tuesday morning.

Toronto police say they were called to the scene of a collision at Gerrard Street East and Carlaw Avenue shortly after 10 a.m.

Const. Clint Stibbe said the woman was on the roadway when the collision occurred.

Initial reports from police had suggested that the victim was elderly, but they have since said she was 56 years old.

The 42-year-old driver of the truck is co-operating with police.

The crash remains under investigation and police want to speak with witnesses.

Mickey Szalai, a former truck driver who uses a mobility scooter himself, says pedestrians should stay back from the edges of curbs and that people using scooters must be more careful.
